(2) Enable circuit logic error
• Confirm that the output from
safety switches or other devi-
ces is input with the same log-
ic (High/High or Low/Low) for
both
SF1 and SF2 terminals.
• Check that the two poles of
SW9 on the control board are
both ON/ON or OFF/OFF.
→ Reset the alarm by executing
Reset (Refer to
